DB2 - Problembeschreibung

Problem IC80998 Status: Geschlossen

NUMA API incompatibility on SLES11 and RHEL6

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
The NUMA APIs that DB2 uses to provide NUMA support have an 
undocumented dependency between the build platform used to 
create DB2 libraries, and the kernel used while running DB2. 
 
The kernels on SLES11 and RHEL6 violate this dependency and are 
thus incompatible with DB2's NUMA support. 
 
If you attempt to enable NUMA support (via the 
DB2_RESOURCE_POLICY registry variable) on either of these 
platforms, you will encounter either of the following errors 
during db2start or db2 activate database.
